Azden IRD-60 Supplementary Manual
CLASSROOM PROVEN
For the past decade, probably no company has had more of their wireless microphone systems installed in classrooms across the country than
Azden. Working with the engineering departments of the leading classroom amplification names, Azden has been at the forefront of the drive to
improve the quality and reliability of sound available in classrooms. Azden has been selected by these companies because of our long experience
in producing reliable RF and infrared products, not for the "stage" but for everyday applications, especially classrooms and conference rooms. Now,
in addition to our continued partnerships, Azden is proud to introduce its own lineup of products, engineered specifically for the classroom.
THE ADVANTAGES OF INFRARED
Infrared wireless microphone systems are the best solution for classrooms. In today's RF saturated world a regular (VHF or UHF) microphone system
risks interference from a variety of other devices and sources. Cell phones, radios, TV, PA systems, police and emergency service systems, etc., can all
interfere with VHF and UHF, but not with IR. Furthermore, infrared is perfect for classroom audio, since, unlike the other systems, IR is short-range,
cannot penetrate walls, and is line-of-sight. This means that a school can have as many classrooms as desired with individual audio systems, without
fear of interference. Since the Azden system is dual-channel, the teacher can have one microphone and a second person can also have a microphone.
In addition, since each classroom system is on the same pair of channels, teachers can go from room to room without having to switch microphones.
COMPLETE CLASSROOM SYSTEM
Although you can purchase components separately to customize your own system, Azden provides two complete systems
(IR-CS and IR-WS) which include: an IR receiver with ample power for 4 ceiling or 4 wall-mounted speakers and a built-in
sensor array (IRR-30P), a small, lightweight chest-worn microphone/transmitter (IRN-10), a pass-around handheld
microphone/transmitter (IRH-15c), an external ceiling-mounted sensor (IRD-60), and 4 high-quality in-ceiling speakers
(ACS-6.5) or 4 compact wall-mounted speakers (AWS-4.5). All you need to complete the installation is the wiring for
the speakers and sensor.
IRR-30P RECEIVER
The heart of the Azden infrared system is the IRR-30P powered, dual-channel receiver. It allows you to use and control the volume of 2 wireless
microphones simultaneously, either for "team-teaching, or to use the handheld microphone for student pass-around. The receiver also has 2 stereo

auxiliary inputs so that other line-level devices (CD players, MP3 players, VCRs, etc.)
can be attached and played through the system. The teacher can also send the audio to
a recorder or video camera, using the line-level preamp-level jack. For bigger rooms or
odd-shaped rooms up to 3 additional external sensors can be attached. With all 4 of the
ceiling speakers attached to the IRR-30P, sound is spread equally throughout the room,
allowing all students to hear equally.

IRN-10 MICROPHONE
A lightweight, chest worn, microphone/transmitter, it comes with an adjustable lanyard. It is both a microphone and infrared
transmitter which wirelessly "links" the teacher to the IRR-30P receiver. It has a specially designed internal microphone array
which provides great sound pick-up. With two switchable channels, a teacher can go from classroom to classroom with the same
microphone! With just two "AA" batteries (alkaline or rechargeable) the microphone can be used the entire school day without
recharging or changing batteries.

IRD-60 SENSOR
In most classroom situations, a single well-
positioned IRD-60 external IR sensor provides
complete classroom coverage. Mounting is easy,
and the sensor is connected to the IRR-30P
receiver with standard coaxial wire.

ACS-6.5 IN-CEILING SPEAKER
The ceiling speaker was designed to provide optimum performance for the teacher’s voice in addition to
audio from other sources (CD/MP3 player, VCR, etc.). Each speaker features a sealed-back enclosure and
6.5" polypropylene midrange/woofer to produce natural bass response, while the coaxially-mounted 1"
polycarbonate tweeter provides superior high frequency response. Easily flush-mounted in any drop-ceiling,
four of these speakers provide smooth, evenly distributed sound throughout the classroom. All students can
enjoy enhanced audio equally

AWS-4.5 WALL-MOUNT SPEAKERS
In those classrooms that don’t have drop-in ceiling tile, using four of these wall-mount speakers provides
evenly distributed sound throughout the room. Easily mounted to the wall using the included brackets, each
speaker features a small, high-impact polycarbonate cabinet fitted with a 4.5" midrange/woofer, a 1" soft
dome tweeter and a .5" super tweeter – producing well-balanced, smooth audio.

IRH-15c HANDHELD MICROPHONE
The perfect handheld "pass-around" microphone for student participation, this
dual channel microphone/transmitter, operates on the channel that the teacher is
not using. It is powered by two "AA" batteries (alkaline or rechargeable) and is
compatible with all Azden infrared models.
